    Is there a shortcut instead of doing the problem 21 times?

    most definitely it's called using scientific notation and rules for exponents

    the general format for scientific notation a*10^n where a is greater than zero and less than 10 n is an integer

    when you multiply numbers/variables with the same base you add the exponents when you divide numbers/variables with the same base you subtract the exponents

    quotient is what you get when you divide

    Okay, so in this case we are dividing. Tell me if I am doing this correctly, 21-3? Then 2x10 and 8x10.

    scientific notation is used to work with very large and very small numbers properties for multiplication says you can rearrange how you combine terms to multiply them regroup to work with like terms use arithmetic and rules of exponents format the result in standard format (a*10^n)

    Can you give me a quick example of regrouping please?

    Well, I forgot how to regroup like terms and the rest i just am stumped at....

    using scientific notation we group the 10^n terms

    then apply the rules for exponents to simplify that part

    I am reviewing the steps how about if you try the original problem by yourself and the let me know if you have any questions

    start by regrouping the "regular" and the "powers of 10"
